Summative Diagnosis:
Cardiovascular phenotype: Complex congenital heart defects including persistent truncus arteriosis (PTA), atrioventricular septal defect (AVSD), and right sided aortic arch (RAA).
Noncardiovascular phenotype: Abnormal thoracic and abdominal organ situs anomalies, such as asplenia, left pulmonary isomerism, and liver isomerism. Also observed were cleft palate, preaxial digit duplication, malalignment of the sternovertebrae, and cystic kidneys.

Fyler Codes
The Fyler code developed by The Boston Children's Heart Foundation in Boston Children's Hospital provides a hierarchical clinical diagnosis of congenital cardiovascular defects and other disorders. These codes are used to delineate pathology in the mutant mouse models that parallel human disease and can be cross referenced to the International Pediatric and Congenital Cardiac Code (IPCCC) (http://www.ipccc.net/).
